Abstract
The composition of the unsaponifiablc fraction, and of the fatty acid fraction of the liver oil of Heptranchias pectorosus has been determined, Since Ξ±βglyceryl ether esters are a major constituent of the oil, the component Ξ±βglyceryl ethers of the unsaponifiable fraction have been quantitatively determined and their relationship to the fatty acids discussed.
